Though not common, one can become dependent to benzos in as little as two weeks time when taken daily. Increase the time taken and the possibility increases dramatically and when I say dependent I mean needed to cope. Then once one tries to stop, unlike the opiates, they can experience horrendous withdrawals that can last weeks, months even years....no foolin'.
Considering you have a history of dependency I advise you use with extreme caution and very infrequently, if even at all. What 5 mgs does to you now can easily require 10 mgs in just a few days time to get the same effect. It is just way too easy to pop a pill rather than to make the effort to learn coping skills. Sad but true.
